This article explores the nature of self-awareness and its cultivation methods, pointing out that many people generally lack accurate recognition of themselves. The article first defines self-awareness as comprising two aspects: internal self-awareness (understanding oneself) and external self-awareness (understanding how others perceive oneself). Then, the article analyzes two main reasons for insufficient self-awareness: cognitive blind spots (emotional and cognitive biases) and self-idolatry. Finally, the article elaborates on practical methods for cultivating self-awareness, including enhancing internal self-awareness through correct self-reflection, life experience methods, mindfulness training, and miracle questioning, as well as strengthening external self-awareness by seeking feedback from compassionate critics and using the 3R model.
